BestPractice: Navigation

Hello,

I would like to realize a layer based navigation. Each entry may have 0...n sublevels. The XML, which describes this navigation looks like the following:

</entry>

</navigation>

Secondly, there exists an XML, which describes the content of the page itself:

<page>

<title>Blabla</title>

<content>This is the content</content>

</page>

Now, I have got problems to bring the navigation informations dynamically into the XSL. I would like to describe each site in the sitemap and aggregate the navigation-XML and the page-XML:

<map:match pattern="foo">

<map:aggregate element="page">

<map:part src="" />

<map:part src="" strip-root="true" />

</map:aggregate>

<map:transform type="xsl" src="" />

<map:serialize type="html" />

</map:match>

Now, I would like to get the name of the actual position on the page. Like this: "You are in area: Foo". Therefore I have to compare the given navigation path with the navigation.xml and extract the content of a element called "name" or/and "url" for example.

In my own opinion, I have two choices but I don't know which one of these works well...

The first one is to give the XSL the actual path of the position via <map:parameter> in <map:transform>. Is this possible?

The second one is to write an own action class/XSP, which gets the actual path via parameter, extracts the necessary informations from the navigation.xml and returns the values as attributes.

The main question is: How can I extract the specified content of navigation.xml depending on a parameter?

Is there a better way, to realize this? A best practice?

Thank you very much.

Regards

Stephan Niedermeier
